From 6b9ab65163528239c9fbf10053427513513e6ab0 Mon Sep 17 00:00:00 2001 From: Fabricio Voznika Date: Fri, 3 May 2019 09:41:08 -0700 Subject: Skip flaky ClockGettime.CputimeId take 2 The test also times out when GCE machine has 2 CPUs. I cannot repro it locally with a 2 CPU cgroup though. Let's skip the test when there are 2 CPUs to stop the flakiness and retest it once the fix is available.
